              縫洞型油藏非均質性非常嚴重,儲層基質物性差,基本不含油,產油部位主要在溶洞、裂縫發育段,鉆井過程中如果鉆遇溶洞、裂縫發育帶,則油井產能高。這類油藏試井曲線不僅種類多,而且部分曲線形態復雜。軟件以縫洞型油藏壓力恢復試井曲線特征為研究對象,結合勘探開發期間的地震、地質、測井、錄井等數據。以力學三大守恒定律為基礎,建立井-縫-洞-地層流體流動模型;采用復雜模型的簡化方法和方程求解方法,得到縫洞型油藏試井分析典型曲線;采用試井分析方法和全歷史計算方法;形成縫洞型油藏試井分析理論及方法體系。

              縫洞型油藏試井分析模型建立:針對縫洞油氣藏的儲層特點,對縫洞型油藏滲流理論進行研究,建立縫洞型油藏試井新模型,對新模型方程進行求解,研究縫洞型油藏試井全歷史擬合方法。

              縫洞型油藏試井分析方法研究:根據縫洞型油藏的典型曲線特征和無量綱參數的定義,給出圖版擬合方法,通過圖版擬合給出試井解釋中所需變量(如滲透率、表皮系數及洞體積等)的表達式。對壓力恢復曲線給出無量綱Horner圖形擬合計算方法等。

              縫洞型試井分析在新疆西北油田得到應用,可以得到了縫洞型油藏的相關解釋結果(溶洞體積、洞距離、洞波動系數、洞阻尼系數、裂縫體積等)。

              The heterogeneity of fracture-hole type reservoir is very serious, the basic reservoir material physical properties are poor and basically oil-free. The oil production is mainly in hole and fracture development section. If hole and fracture development zones are drilled in the drilling process, the productivity of oil wells will be high. There are not only many kinds of well testing curves in this kind of reservoir, but also some of them are complex in shape. The software takes the characteristics of pressure recovery well testing curve of fracture-hole reservoir as the research object, combined with seismic, geological, well testing/logging and other data during exploration and development. Based on the three conservation laws of mechanics, the well-fracture-hole-formation fluid flow model is established, the typical curve of well testing analysis of fracture-hole reservoir is obtained by using the simplified method and equation solution method of complex model, the well testing analysis method and the whole history calculation method are adopted, and the theory and method system of well testing analysis of fracture-hole reservoir are formed.

              The well testing analysis model of the fracture-hole type reservoir is established: In view of the reservoir characteristics of the fracture-hole oil and gas reservoir, the seepage theory of the fracture-hole type oil reservoir is studied, a new model of the fracture-hole type oil reservoir well testing is established, and the new model equation is solved, and the full-history simulation method of the fracture-hole type oil reservoir well testing is researched.

              The research of well testing analysis method of the fracture-hole type reservoir is as follows: According to the characteristic of the typical curve and the definition of the dimensionless parameters, the chart simulation method is given, and the expression of the required variables (such as permeability, skin factor, hole volume, etc.) in the well testing interpretation is given by the chart simulation. The dimensionless Horner graph simulated calculation method and so on are given to the pressure recovery curve.

              Fracture-hole well testing analysis has been applied in northwest Xinjiang Oilfield, and the related interpretation results (hole volume, distance, fluctuation coefficient, damping coefficient, fracture volume, etc.) of fracture-hole reservoir can be obtained.
