OPTIMIZED DESIGN TECHNIQUE FOR THE HORIZONTAL WELL DEVELOPMENT IN XUSHEN VOLCANIC GAS RESERVOIRS
摘要
Abstract
Xushen Gasfield belongs to deep large-size low or ultra-low-permeability volcanic gas reservoirs, which is characterized by the fast lateral lithology and lithofacies changes, limited favorable facies-belt range and generally well-developed water layers in the bottom of gas reservoirs; the reservoirs are mainly composed of Type II and Type HI ones with poor physical properties, and moreover the gas wells are initially produced in the form of fracturing; the current seismic technologies are difficult to accurately predict the characteristics of the reservoir distribution and natural fracture development. In light of the complex geological properties of the volcanic gas reservoirs and the serious difficulty in horizontal well development design, the optimized design technique of the well suited for the properties is established through many-year development practice and deep study. The acquired apparent application effects have provided powerful technical support for increasing the developed reserves degree and entire development benefits of Xushen volcanic gasfield. And furthermore these achievements possess guidance and reference significances for the horizontal well design in such similar gas reservoirs.关键词
