Drilling and construction technology of Well Eheye 3 in the western Hubei
摘要
Abstract
The shale gas parameter Well Eheye 3 is located in the Yidu-Hefeng complex anticline and Hefeng syncline of the Enshi Xiang'exi Fold Belt in Hubei Province.The main purpose of drilling is to explore the sedimentary shale gas of the Permian Dalong Formation platform basin facies,as well as the mixed shelf sedimentary shale gas of the Qixia Formation.The designed well depth is 2300m,and the completed drilling depth is 2326m.This article introduces the drilling and construction situation of Eheye 3 well,focusing on the treatment of non return leakage in the shallow Jialingjiang Formation on the surface,the selection of high hardness siliceous limestone drill bits for the Gufeng and Maokou formations,and the design of anti inclination straight bending shell screw drilling tool combinations.Research has been carried out to improve drilling efficiency.The first shale gas parameter well independently established by the China Geological Survey has been completed,and physical data of target layer rock cores have been obtained.New discoveries have been made in the exploration of Permian Dalong Formation shale gas and Qixia Formation oil and gas in western Hubei,expanding the exploration area and new layers of Permian shale gas in western Hubei.The investigation and evaluation of shale gas in western Hubei have been conducted.Provided important technical support for development.关键词
