FEATURES OF THE ACID AND ALKALINE DIAGENETIC ENVIRONMENT OF TIGHT SANDSTONES AND THE CONTROL OF THE RESERVOIR PHYSICAL PROPERTIES: A CASE STUDY OF THE LINXING AND SHENFU DISTRICT, EASTERN ORDOS BASIN

The pH value of plaeofluid exerts great influence on the formation of the secondary pores of sandstones.In the paper, the control of the acid and alkaline diagenetic fluid environment on the reservoir quality was analyzed in the Upper Paleozoic tight sandstones in the Ordos basin.Based on the plenty of survey of casting thin section, scanning elect

Pachydermodactyly (PDD) is a rare, acquired idiopathic form of digital fibromatosis.PDD typically presents as asymptomatic swelling of the second to fourth reptile supplies proximal interphalangeal joints bilaterally in young males.Here, we present an acquired unilateral PDD in a Saudi boy with emphasis on the clinical, radiological, and histopatho

Background.Posterior fossa epidural hematomas represent 7-14% Lip Tint of all traumatic intracranial epidural hematomas.They are most frequently encountered posttraumatic mass lesions in the posterior fossa.The aim of this study was to identify clinical features that could lead to the early diagnosis of posterior fossa epidural hematoma.Methods.Bet
