Efficient Well Construction in Yingmai Block in Tarim

As of September 16, the Production Capacity Construction Division of Tarim Oil and Gas Field has promoted the integration of engineering geology in Yingbuli Block, and the 7 completed horizontal Wells have all obtained high-yield oil flow, laying a solid foundation for long-term stable production, quality improvement and efficiency improvement in Yingbuli block.

The Yingmeili block has a variety of target layers. At present, oil and gas reservoirs have been found in Cambrian, Ordovician, Silurian, Cretaceous and paleogene systems. Stratiform edge water condensate reservoir, massive bottom water condensate reservoir, stratiform edge water reservoir, massive bottom water reservoir and fracturecave reservoir are developed. Of the seven Wells built and produced this year, four are stratified edge water reservoirs, and the other three are stratified edge water condensate reservoirs, blocky bottom water condensate reservoirs with bottom oil, and blocky bottom water reservoirs.

Geological engineering integration, high quality and efficient well construction. For different types of oil and gas reservoirs, the Production capacity construction Division of Tarim oil and gas field gives full play to the advantages of geological engineering integration. When compiling the drilling geological design, the engineering geology is fully integrated to optimize the horizontal well trajectory, so as to ensure the new well can be implemented safely and quickly. In the course of horizontal well drilling, geological model should be established in time according to the specific conditions of new Wells, geological engineering should be combined with the formulation of horizontal well drilling scheme to guide horizontal well drilling with "one well and one policy".

At the same time, the oil and gas production capacity construction division constantly sum up experience lesson, on the premise of ensure the safety of drilling, the application of new techniques, new technologies, deepen the geological understanding, optimization source, achieve the goal of authors efficiency, for the subsequent YuDong YingMaiLi blocks 104 h, YuDong 34-101-5 h, British buy 12 h three horizontal Wells in the implementation of the ready knowledge reserves, to ensure that the reservoir drilling rate.
