Users of recommendations set forth herein are reminded that constantly developing technology and specialized or limited operations do not permit complete coverage of all operations and alternatives. Recommendations presented herein are not intended to inhibit developing technology and equip

8、ment improvements or improved operating procedures. These recommended practices are not intended to obviate the need for qualified engineering and operations analyses and sound judgments as to when and where these recommended practices should be utilized to fit a specific underbalanced drilling appl

9、ication.Recommendations presented in this publication are based on this extensive and wide-ranging industry experience. The goal of these recommended practices is to assist the oil and gas industry in promoting personnel safety, public safety, integrity of the underbalanced drilling equipment, and p

10、reservation of the environment for land and offshore underbalanced drilling operations and these recommended practices are published to facilitate the broad availability of proven, sound engineering and operating practices. This publication does not present all of the operating practices that can be

11、 employed to successfully conduct underbalanced drilling operations. Practices set forth herein are considered acceptable for accomplishing the job as described; however, equivalent alternative installations and practices may be utilized to accomplish the same objectives. The formulation and publica

12、tion of API recommended practices is not intended, in any way, to inhibit anyone from using other practices. Furthermore, individuals and organizations using these recommended practices are cautioned that underbalanced drilling operations must comply with requirements of applicable federal, state, o

13、r local regulations and these requirements should be reviewed to determine whether violations may occur. Any manufacturer marking equipment or materials in conformance with the marking requirements of an API standard is solely responsible for complying with all the applicable requirements of that st

16、d Pressure Drilling Committee consisting of representatives from various IADC member companies, represent a composite of the practices employed by various operating companies, service companies and drilling contractors in underbalanced drilling operations. In some cases, a reconciled composite of th

17、e various practices employed by these companies was utilized. The Committee acknowledges the Canadian Association of Drilling Contractors (CAODC), the Canadian Association of Petroleum Producers (CAPP), Petroleum Services Association of Canada (PSAC) and the Alberta Energy Utilities Board (AEUB), an

18、d in particular the Drilling and Completions Committee (DACC) for their effort in developing guidelines related to underbalanced drilling in the Canadian environment, which are the basis for this document. This publication is under the jurisdiction of the American Petroleum Institute, Upstream Segme

19、nts Executive Committee on Drilling and Production Operations. Underbalanced drilling is used globally on new wells and to deepen or side-track from existing well bores. Underbalanced drilling operations are being conducted with full regard for personnel safety, public safety, and preservation of th

20、e environment in such diverse conditions as urban sites, wilderness areas, ocean platforms, deepwater sites, very hot barren deserts, cold weather areas including the arctic environment and wildlife refuges. As tools and equipment continually improve and develop, the technology has been applied in m

21、any geological formations including oil and gas reservoirs and on sour wells thus driving the need for globally accepted standards and safe operating practices. Furthermore, this publication includes use of the verbs “shall” and “should” whichever is deemed the most applicable for the specific situa

22、tion. For the purposes of this publication, the following definitions are applicable:Shall: As used in a standard, “shall” denotes a minimum requirement in order to conform to the specification.Should: As used in a standard, “should” denotes a recommendation or that which is advised but not required

23、 in order to conform to the specification. Changes in the uses of these verbs are not to be effected without risk of changing the intent of recommendations set forth herein. Recognizing the varying complexity and risk associated with drilling wells classified as IADC Level 1 as compared to IADC Leve

24、l 4 or 5, this document is prepared from the perspective of an IADC Level 1 or 2 well. Therefore, the end-user is advised to replace the verb “should” with “shall” for wells classified as IADC Level 4 or 5.Nothing contained in any API publication is to be construed as granting any right, by implicat

Neither should anything contained in the publication be construed as insuring anyone against liability for infringement of letters patent.This document was produced under API standardi

26、zation procedures that ensure appropriate notification and participation in the developmental process and is designated as an API standard.
