摘要:
煤層氣儲層壓裂產能受地質因素和工程因素共同影響。分析不同壓裂產能的地質影響因素,綜合不同區域地質影響因素進行壓裂區優選,建立適用于鄂東緣H區的壓裂產能預測分類標準。鄂東緣H區煤體結構主要劃分為原生結構煤、碎裂煤、碎粒煤,測井信息與不同煤體結構之間的關系隨著煤體結構越破碎,井徑擴徑越嚴重,深電阻率逐漸降低; 煤層厚度、煤體結構、含氣量、地應力、天然裂縫是影響壓裂產能的地質主控因素。對21口新井32個煤層氣壓裂層段進行了壓裂產能預測檢驗,預測符合率達84.4%。
Abstract:
The post-fracturing productivity of coalbed methane(CBM)reservoirs is affected by geological and engineering factors. In this paper, geological factors affecting post-fracturing productivity are analyzed, target fracturing zones are selected based on regional geological factors, and classification criteria are established for predicting post-fracturing productivity in the H area on the eastern edge of Hubei Province. Coal structures in the H area are mainly divided into undeformed coal, fragmented coal and granulated coal. Log data indicate that the more fragmented the coal structure, the more serious the borehole is enlarged, and the lower the deep resistivity. The thickness of coal seam, coal structure, gas content, in-situ stress and natural fractures are controlling geological factors affecting post-fracturing productivity. Tests on 32 fractured coal seams in 21 new wells demonstrate that the productivity prediction is coincident by 84.4%.
