14、now Subcommittee 10) formed aTask Group in the mid-1980s charged with updating the squeeze-cementing well-simulationtest schedules in API Spec 10 (now API Specications 10A and RP 10B) using a large col-lection of new temperature data. Temperatures in the squeeze schedules had not beenupdated since 1

15、953. The collection of new temperature data was the largest ever available forconsideration in developing temperature correlations for cementing test schedules. Eventu-ally, the scope of the Task Groups work expanded to update all the well-simulation testschedules using the new temperature data. The

16、 potential benet to the industry was great.One goal of the Task Group was to develop the most accurate temperature correlationsfrom the data. Several methods of developing correlations from data were investigated. Rig-orous and thorough analysis of the data was required and eventually completed. Fin

17、ally, acorrelation was developed using statistical regression techniques that provided the lowesterror based on the data.The correlation predicted temperatures that were higher than any previous temperatures inwell-simulation test schedules at depths shallower than about 10,000 feet. This was alarmi

18、ngto users of the test schedules since each set of schedules had been used for about 20 yearswithout evidence of widespread problems with the predicted temperatures.The new temperature data was scrutinized once more. The correlation methods and resultswere reviewed. Previous temperature data sets an

19、d the correlations developed from themwere investigated. All of this was done to:1. Understand the representative range of data contained in each set of data. 2. Determine and understand the methods used to develop the correlations. 3. Compare previous methods to the methods selected by this Task Gr

20、oup and criticallyevaluate each. 4. Select the best methods for development of correlations from the new temperaturedata.Results of this entire effort are summarized in this report. It is our desire to improveunderstanding about how temperature correlations used in API well-simulation test sched-ule

21、s were developed. Each data set used to develop correlations was not representative of allcementing operations. Even the most precise correlations developed from the data may notreect true cementing temperatures. Therefore, each correlation has limitations on the accu-racy of predicted temperatures

22、for a specic cementing operation. However, we rmlybelieve that the temperature correlations prepared by us and those before us are of value tothe industry.Finally, this document has been prepared to leave a clear understanding of the data, analy-sis, and methods upon which the recommendations made a

23、nd adopted by API Committee 10in June 1991 are based. We leave this document as a tool to assist those who may performsimilar work in the future.API publications may be used by anyone desiring to do so.
