This study estimates the reservoir properties of the Carboniferous deposits in the southeastern part of the Lublin Basin based on diagenetic and sequence stratigraphic patterns. Depositional sequences distinguished represent the following environments/processes: shallow clay and carbonate shelves, deltaic, fluvial, and hyperconcentrated flow while parasequences (cyclothems), maximum regression-initial transgression surfaces (T), maximum flooding surfaces (MFS) and also lowstand (LST), transgressive (TST) and highstand (HST) systems tracts have been recognised. Sequences recognized may be linked to the global stratigraphic division of the Carboniferous, thus providing a time framework and environmental context for petrographic and petrophysical examinations. The reservoir properties were found to be clearly controlled by depositional environment, diagenetic history and burial. The best properties were recognized in sandstone lithosomes formed in braided, meandering and anastomosed fluvial channels and hyperconcentrated flows which fill the incised valleys and belong to the LST. They are characterized by good porosity reaching up to 15.1%. The TST and HST deposits are represented chiefly by claystones, mudstones and limestones that formed in a shallow shelf and deltaic environment, being sealing intervals. The diagenetic history of sandstones comprises eo-, meso- and telodiagenetic phases. The major processes acting during the first of these were mechanical compaction, dissolution of mineral grains, formation of predominantly quartz overgrowths around the quartz grains, and crystallization of kaolinite. During mesodiagenesis, cementation with quartz, kaolinite and carbonates continued along with the formation of dickite and fibrous illite; moreover, mineral grains were dissolved and chemical compaction set in. The effects of telodiagenetic processes were feldspar dissolution and precipitation of kaolinite. During diagenesis the maximum temperature affecting the Carboniferous deposits was ~120°C. Compaction and cementation were the main factors responsible for the reduction of porosity by approximately 55 and 38%, respectively. One of the major diagenetic processes was dissolution resulting in the formation of secondary porosity. The Serpukhovian and Bashkirian sandstones from sequence 11 show good reservoir potential, while those from sequences 6, 9, 10, 12–14 only fair potential.

这项研究根据成岩作用和层序地层学模式估算了卢布林盆地东南部石炭系沉积物的储层性质。区分的沉积层序代表以下环境/过程：浅层粘土和碳酸盐层架，三角洲，河流和超浓缩水流，副序列（旋回），最大回归初始海侵面（T），最大洪泛面（MFS）和低水位（LST） ），侵入式（TST）和高海拔（HST）系统段已被识别。公认的层序可能与石炭纪的全球地层划分有关，从而为岩相和岩石物理检查提供了时间框架和环境背景。发现储层性质明显受沉积环境控制，成岩史和埋葬史。最好的性质在形成于辫状，蜿蜒和吻合的河流通道和高浓度水流中的砂岩卵石中得到了公认，这些水流充满了切开的山谷并属于LST。它们的特点是孔隙率高达15.1％。TST和HST矿床的主要代表是在浅层架和三角洲环境中形成的粘土岩，泥岩和石灰岩，它们是封闭的间隔。砂岩的成岩史包括成岩，中观和成岩作用。在这些过程的第一个过程中，主要的作用是机械压实，矿物颗粒的溶解，在石英颗粒周围形成主要的石英过度生长以及高岭石的结晶。在中成岩作用中，与石英胶结，高岭石和碳酸盐继续发生，同时有重沸石和纤维伊利石形成。此外，矿物颗粒被溶解并进行化学压实。成岩作用的影响是长石的溶解和高岭石的沉淀。在成岩过程中，影响石炭纪沉积物的最高温度为〜120°C。压实和胶结作用是导致孔隙率分别降低约55％和38％的主要因素。主要的成岩作用之一是溶解，导致形成次级孔隙。层序11的Serpukhovian和Bashkirian砂岩显示出良好的储层潜力，而层序6、9、10、12-14的砂岩只有相当的潜力。矿物颗粒溶解并进行化学压实。成岩作用的影响是长石溶解和高岭石沉淀。在成岩过程中，影响石炭纪沉积物的最高温度为〜120°C。压实和胶结作用是导致孔隙率分别降低约55％和38％的主要因素。主要的成岩作用之一是溶解，导致形成次级孔隙。层序11的Serpukhovian和Bashkirian砂岩显示出良好的储层潜力，而层序6、9、10、12-14的砂岩只有相当的潜力。矿物颗粒溶解并进行化学压实。成岩作用的影响是长石溶解和高岭石沉淀。在成岩过程中，影响石炭纪沉积物的最高温度为〜120°C。压实和胶结作用是导致孔隙率分别降低约55％和38％的主要因素。主要的成岩作用之一是溶解，导致形成次生孔隙。层序11的Serpukhovian和Bashkirian砂岩显示出良好的储层潜力，而层序6、9、10、12-14的砂岩只有相当的潜力。压实和胶结作用是导致孔隙率分别降低约55％和38％的主要因素。主要的成岩作用之一是溶解，导致形成次生孔隙。层序11的Serpukhovian和Bashkirian砂岩显示出良好的储层潜力，而层序6、9、10、12-14的砂岩只有相当的潜力。压实和胶结作用是导致孔隙率分别降低约55％和38％的主要因素。主要的成岩作用之一是溶解，导致形成次级孔隙。层序11的Serpukhovian和Bashkirian砂岩显示出良好的储层潜力，而层序6、9、10、12-14的砂岩只有相当的潜力。
